Abstract

The aim of the invention is a lighter construction for a car jack and thus a weight advantage for the vehicle. Said aim is achieved whereby said jack, with a support body standing on the ground (4), which comprises a support column (1), a foot (2) pivotably attached thereto and a carrying arm (5). Said arm is fixed to the support column such that it may rotate about a defined horizontal axis, may be directly or indirectly raised or lowered relative to the ground (4), by means of a displacement spindle (7), have a fixed or pivotable support piece on the free end (6) thereof and on the other end, extending into the support column (1), comprises suitable controlling means which displace a control slide (10) parallel to the longitudinal direction of the support column (1) such that the control slide occasionally rests with the end (19) thereof on the base surface (3) of the foot (2). Said aim is achieved whereby a dog (21) is arranged on the inner side of the base surface (3), in front of the end (19) of the control slide (10).

Description

Car jack

The present invention relates to a kind of car jack of the preamble by claim 1, it have one stand on upright body on the base and one can be on this upright body around the fixing carriage of a horizontal steering shaft motion.

Can be placed in that support and one one end on the basis is hinged on the support and be can relative support the hoist car jack of the carriage swung of lifting process by an installation foot for having one, at first should note, the support of car jack vehicle basic or to be hoisted relatively assembles with a definite angle, just is installed on the basis.Only in this way can avoid just that load is received improperly when the lifting of vehicle, car jack also can slip in some cases, because the active line of load does not extend through installation foot.For in the use of car jack, make unskilled people easily on the basis with the correct gradient mounting vehicle elevator of its support, by among EP 0 688 736 A1 as can be known, use a control slide that can vertically move on support by the motion of carriage, pin is controlled to the setting angle of determining a car jack on this support in its motion by being automatically connected in.

Wherein, control slide stands on the areal of support inboard of pin with its end.The bending that joystick is designed in its end is forward still backward decided according to the position of the motion conditions of car jack and the attachment point on vehicle.Particularly when joystick stands on the pin obliquely, cause big component here, this is disadvantageous, and consequently, it is the strongest joystick must to be configured to bending, and the guiding below the support place also will be constructed by force accordingly.The rough sledding that can cause requirement material input to improve like this.

Task of the present invention is that the design vehicle elevator is lighter, so that obtain the weight advantage of vehicle thus.

This task solves according to the invention through the features of claim 1.Embodiment preferred and alternative are described in claim 2 and 3.

By in the inboard of areal of support, a block was set before the end of control slide, make the clear and definite location, end of control slide.When not having so-called complete lifting, this flexure stress of having an effect on control slide obviously reduces.Therefore, control slide when the guide rod supporting power is identical, can design thinlyyer on pin as following guide piece.Particularly design during block as the substrate crimping that in areal of support, forms, this can be achieved not having additional materials and improve under the situation of manufacturing expense.

One embodiment of the present of invention illustrate in the accompanying drawings and are further described below.This unique figure has shown by the cross section according to car jack of the present invention.

In car jack according to embodiment, relate to one have one can rotating hinged pin single armed articulated vehicle elevator.This car jack has as a upright body described in Fig. 1, and it is made up of a support 1, but a pin 2 is hinged on gyroscopic movement on its supporting end face.This pin 2 stands on the pedestal 4 with its areal of support 3.In the superincumbent scope, but a carriage 5 similarly is articulated on the support 1 gyroscopic movement.Free end 6 places at carriage 5 are equipped with a load-carrying unit of not drawing, and it is complementary with the antagonistic force of the vehicle that will be raised.This load-carrying unit can be same make flip-flop movement or come out with other formal construction, and for example catch in the expansion weld seam for the treatment of the lifting vehicle.Support 1 and carriage 5 are interconnected by a transmission shaft 7.The nut of not depicting that slides forms such result on the upper end 8 of support 1, promptly when rotating drive shaft 7, this transmission shaft forms with a wind 9 usually, carriage 5 is with respect to support 1 deflection, therefore make 6 liters of the free ends of carriage 5 or fall, thereby make the lifting and the decline of vehicle with respect to substrate 4.

In the example of described car jack, but the swing position that is hinged on the pin 2 of the gyroscopic movement on the support 1 is controlled by control slide 10.The detailed explanation in Fig. 2 to Fig. 4 of this control slide 10.

Not only pin 2 but also support 1 and carriage 5 are all formed by the sheet material manufacturing, and have a kind of U-shaped cross section.The edge of a wing and the edge of a wing, two sides in the middle of they have one.In the end relative with free end 6 of carriage 5, the edge of a wing, side 11 of carriage 5 forms one and surpasses about 180 ° tooth portion, here is a knuckle-tooth portion.The middle edge of a wing 12 of carriage 5 does not reach tooth portion place.Form two sector sections 13 here.In the sphere of action of the tooth portion of carriage 5, the 14 projection ground, the middle edge of a wing of carriage 1 outwards expand.By this projection 15, obtain the free avidity of a sector section 13 on the middle edge of a wing 14 of relative support 1.

Control slide 10 is made up of a targeting part 16 and thrust part 17 two parts.In an embodiment, targeting part 16 is formed and is had the cross section of a W shape by sheet material.As anti-engagement, in targeting part 16, introduce hole 18, the tooth of sector section 13 meshes therein.Thrust part 17 is formed by a bar in an embodiment, and it has an elbow 20 at its 19 places, lower end.Control slide 10 is squeezed on the middle edge of a wing of the pin 2 that forms bearing surface 3 with its lower end 19.Look how many angles of elbow 20 bending, how much length, the end 19 of control slide 10 is placed on another aspect on the areal of support 3 of pin 2.The controller performance of pin 2 is applicable to will be by the situation of the vehicle of lifting thus.

On the medial surface of areal of support 3, a block 21 was housed before the end 19 of control slide 10.In an embodiment, this block 21 forms by a horizontal crimping that inwardly forms arch in areal of support 3.Apparently, this block must be applicable to the motion conditions of car jack, just according to structure design, particularly according to the elbow of the end 19 of control slide 10, crimping must have another position, and it relates to the hinge-point 22 of the pin 2 on support 1.When the small lot car jack, form the pin 2 have a flat areal of support 3, then with a rivet or weld stay, economic implications is arranged like this as block 21.Though so fine improved the weight of pin 2, when small lot, brought advantage economically.
